Thepresentinvention constitutes an improvement on filters employingi3; casing and superposed cells confined ,wjthinthebalsing, asillustrated, for instance;, ;inim y application Serial No. 277,896,filed Septemberll, 1905;

and the gistof the invention lies in the employment of relativelyswinging sections forming the casing, whereby easy access for thepurpose of insertion and removal of cells 2 5 is provided.

The invention is illustrated in the accompanying drawings, in whichFigure 1 represents anelevational view of my improved filter, a portionbeing shown in section; Fig. 2, a horizontal sectional view taken asindicated at line 2 of Fig. 1, the casing-top being removed; Fig. 3, anenlarged broken vertical section taken as indicated at line 3 of Fig. 2,and Fig. 4 a perspective view 3 5 showing the relation of certainpivotal parts. In the construction shown A A represent standardscarrying a cross-bar A with which is adjustably connected a casing-top AA A casing-sections supported on a base A". and connected with thestandards, and B r'emovable cells located within the casing and confinedbetween the top and base thereof.

The bar A is mounted toswing upon the standard A, one end of the barvbeing disenga eably connected with the standard A in a we l-knownmanner, the hook formation of the swinging end of the bar beingindicated in section at a. The bar supports a top-actuating screw awhich in turn is actuated by 5 a shaft a and hand-wheela in a well-knownmanner. i

The casing-section A is equipped with pivotal lugs a, and has hooks aengaging the standard 'A. 5 5 These members may be formed integrally,

with which the,lowersidepofrtliezadj alcentzlug;

The; .1arrangement; is; such-J thatwhen-tthahandleg aiflis movedafromgthe; position of the full lines tothe positionof thej dotted lines shown in Fig. 2 the up er casing- 7 5 Isection will be lifted clear of the ower sec' 'tion, enabling the uppersection to be swung upon its pivot.

Pressure is transmitted from cell to cell of the filter from top tobottom. The liquor enters at the base through an inlet 0 and passes intothe annular chamber 0, between the casing and the peripheries of thecells, from whence it passes through the cells to the central conduit 0andthence to the outlet 0 in the manner described in theabove-designated application. Thus it will be underserves as acontinuous casing, and the cel s are built up from bottom to top, theoperation of the filter be- 90- mg the same as though the casing were ofinte al formation.

en it is desired to remove the cells, the to is raised and swung to oneside. The ce ls are then removed down to or below the 5 junction planeof the upper and lower casingsections, and the upper casing-section then1s raised and swung in a direction to balance the top, enabling thelower cells to be readily reached; The reverse of these operations acroocomplishes the assembling of the parts, the gasket a furnishing aliquid-tight joint between the casing-sections.

'I do notlimit myself todetails of construction.

What I regard asnew, and desire to secure by Letters Patent, is-

1. In a filter, the combination of a casing comprising relatively swining casing-sections having vertical pivota connection, and 1 to oted onthe other of said standards,

filter-cells contained in the casing-sections, V

for the purpose set forth.

2. In a filter, the combination of superposed relatively swingingcasing-sections, a swinging casing-top, and superposed cells locatedwithin the casing-sectlons and confined between the top and bottom ofthe casing, for the pur ose set forth.

3. In a lter, the combination of a stationary lower casing-section, asuperposed oasing-section, a gasket confined between saidcasing-sections, a vertical pivot for the upper section, means forraising the upper section to permit it to be swung on its pivot, acasingtop, and a vertical pivot for the-casing-top, for the purpose setforth.

4. In a filter, the combination of a lower casing section, oppositestandards rising above the same at the sides thereof, a swinging uppercasing-section pivoted on one of said standards, and a swingingcasing-top pivfor the purpose set forth.

5. In a filter, the combination of two superposed casing-sections,pivotal connection between said sections at one side, and a cam locatedat the pivotal connection and serving to elevate the uppercasing-section, for the purpose set fort 6. In a filter, the combinationof a lower casing-section, standards arising from opposite sides of thesame, an upper casin -sectlon having a pivotal lug connected with one ofsaid standards, a cam-ring supported beneath said pivotal lug andequipped with an actuating-handle, and a caslng-top adjustably connectedwith said standards.

7. In a filter, the combination of a lower casing-section, standardsarising at opposite sides thereof, a stationary cam on one of saidstandards, a coacting cam-ring supported thereon, a casing-sectionhaving at one side a pivotal lug supported on the cam-ring and at theother side a hook engaging the opposite standard, avertically-adjustable casing-top having a supporting-bar pivoted on thelastnamed standard and provided with a hook engaging the other standard,and nuts serving to secure the bar to the tops of said standards, forthe purpose set forth.

8. In a filter, the combination of a base, a series of filter elements,surrounded partly by a stationary drum and partly by a movable drumswinging around a vertical axis.
